Phys. Rev. C 9, 1748 (1974) - Published 1 May, 1974

Show Abstract

The nuclear gyromagnetic ratio of the 6728-keV $I^{π} = 3^{-}$ level in ${}^{14}C$ has been determined by observation of the time-dependent intensity modulations caused by static, isotropic hyperfine fields occurring in hydrogen-like ${}^{14}C$ ions recoiling in vacuum. A value $| g | = 0.272 \pm 0.007$ is obtained.

Possible measurement of the vacuum polarization in heavy-ion scattering

Johann Rafelski and Abraham Klein

Phys. Rev. C 9, 1756 (1974) - Published 1 May, 1974

Show Abstract

A measurement of the vacuum polarization potential in nonrelativistic elastic heavy-ion scattering is suggested. We find that in a typical sub- Coulomb barrier event enough momentum is transferred from the projectile to the target nucleus to make the high- $q^{2}$ behavior of the photon propagator observable. The elastic cross section is increased in a typical case by 2.5% above the Rutherford value. Only relative measurements are needed.

Systematics of "quasimolecular" resonances: A search for sub-Coulomb resonant structure in the reactions ${}^{14}N$ + ${}^{14}N$ and ${}^{9}{Be}$ + ${}^{12}C$

D. L. Hanson, R. G. Stokstad, K. A. Erb, C. Olmer, M. W. Sachs, and D. A. Bromley

Phys. Rev. C 9, 1760 (1974) - Published 1 May, 1974

Show Abstract

A correlation between the absence of nonstatistical sub-Coulomb resonant structure in many reactions previously studied and the density of levels in the associated compound (or precompound) nucleus is noted and discussed in terms of the intermediate structure model of nuclear reactions. Such a correlation would predict the absence of structure in the ${}^{14}N$ + ${}^{14}N$ system, in disagreement with a previous measurement of excitation functions for the production of $γ$ radiation. Excitation functions for the reactions ${}^{14}N ({}^{14}N, p) {}^{27}{Al}$ , ${}^{14}N ({}^{14}N, d) {}^{26}{Al}$ , ${}^{14}N ({}^{14}N, α) {}^{24}{Mg}$ , ${}^{9}{Be} ({}^{12}C, α) {}^{17}O$ , and ${}^{9}{Be} ({}^{12}C, p) {}^{20}F$ have been measured in the region of the Coulomb barrier in a search for resonance structure of the "quasimolecular" type observed in ${}^{12}C$ + ${}^{12}C$ scattering. The present measurements of excitation functions for charged-particle production in ${}^{14}N$ + ${}^{14}N$ do not exhibit any correlated resonances. The ${}^{9}{Be}$ + ${}^{12}C$ system at the Coulomb-barrier energy produces ${}^{21}{Ne}$ in a region of excitation where the level density is relatively low and hence could be a reaction in which intermediate structure might be observed. The excitation functions measured for $α$ -particle production show fluctuations, but with no apparent correlations.

Backward $N^{*}$ production in proton-deuteron scattering and nuclear isobar configurations

H. J. Weber

Phys. Rev. C 9, 1771 (1974) - Published 1 May, 1974

Show Abstract

Spectator nucleon isobar production in $pd \to d^{'} N^{*}$ is studied at 0.5-1.0-GeV proton c.m. energy and proposed as a probe of the ( $N N^{*}$ ) content of the deuteron. The $N^{*}$ spectator distribution from the nucleon pickup mechanism has a maximum at large angles and vanishes at 180°, while the background cross sections of $N^{*}$ ' s produced in the elementary $pN \to N N^{*}$ collision and $N^{*}$ 's from a pion-nucleon exchange mechanism peak at 180° and fall of rapidly. For an estimated $N N^{*} (1520)$ probability of 1.5%, a large-angle cross section of ∼ 0.2μb/sr is obtained.

Separable representations of $T$ matrices valid in the vicinity of off-shell points

D. J. Ernst, C. M. Shakin, and R. M. Thaler

Phys. Rev. C 9, 1780 (1974) - Published 1 May, 1974

Show Abstract

The method developed in a previous paper for the construction of separable representations for $T$ matrices is extended. It is shown that the separable representation we propose is valid in the vicinity of specified off-shell points. Since the off-shell points considered include those with arbitrary negative-energy parameters, the method presented here should be of value for the bound-state three-body problem.

Neutron-deuteron differential cross sections at 35.0 and 46.3 MeV

F. P. Brady, W. B. Broste, J. C. Wang, J. L. Romero, and P. Martens

Phys. Rev. C 9, 1784 (1974) - Published 1 May, 1974

Show Abstract

Differential cross sections have been measured for $nd$ and $pd$ scattering at 35.0 and 46.3 MeV. Only cross sections for c.m. angles ≳ 90° have been measured in this work, which is in part a higher-precision remeasurement of earlier $nd$ cross sections and whose main purpose has been to check possible $nd - pd$ differences which appeared in the earlier measurements at 36.0 and 46.3 MeV. Absolute $nd$ cross sections of $≃ 5 %$ precision, obtained by normalization to precision $np$ cross sections, are compared with absolute $pd$ cross sections measured at the University of California at Los Angeles. The differences in this comparison and in the $nd - pd$ relative cross sections measured here are smaller than indicated by the previous measurements. However, some systematic differences do appear to exist at angles near the cross-section minima and beyond.

Analysis of the parity-nonconserving amplitudes of the reactions $n + p \to d + γ$ and $n + d \to t + γ$

Bruce H. J. McKellar

Phys. Rev. C 9, 1790 (1974) - Published 1 May, 1974

Show Abstract

We display the invariant amplitudes for the reaction $n + p \to d + γ$ in the absence of restrictions imposed by parity conservation, and demonstrate that Danilov's result that the circular polarization of the $γ$ depends only on the isoscalar parity-nonconserving interaction, and that the asymmetry of the $γ$ with respect to the neutron spin direction depends only on the isovector parity-nonconserving interaction, holds up to corrections of order $\frac{(μ_{n} + μ_{p} - μ_{d})}{(μ_{p} - μ_{n})} \sim 0.005$ . It is also pointed out that essentially the same amplitudes can be used to describe the reaction $n + d \to t + γ$ .

A method is presented for the treatment of particle-hole residual interactions that is both simple and extremely accurate.

Neutron-deficient isotopes ${}^{64}{Ge}$ and ${}^{65}{Ge}$

R. G. H. Robertson and Sam. M. Austin

Phys. Rev. C 9, 1801 (1974) - Published 1 May, 1974

Show Abstract

The $β^{+}$ decays of ${}^{65}{Ge}$ and the new isotope ${}^{64}{Ge}$ have been studied by $γ$ -ray spectrometry with chemically separated sources. Measured half-lives are 30.0 ± 1.2 sec for ${}^{65}{Ge}$ and 63.7 ± 2.5 sec for ${}^{64}{Ge}$ . The decay-scheme studies have been supplemented by investigation of the ${}^{64}{Zn} (p, n γ) {}^{64}{Ga}$ and ${}^{64}{Zn} ({}^{3}{He}, t) {}^{64}{Ga}$ reactions, and the mass excess of ${}^{64}{Ga}$ was found to be -58.819 ± 0.008 MeV. Excitation functions for the ( ${}^{3}{He}, 2 n$ ), ( ${}^{3}{He}, 3 n$ ) and ( ${}^{3}{He}, p 2 n$ ) reactions induced on ${}^{64}{Zn}$ are presented for comparison with other work. The question of the role of ${}^{64}{Ge}$ in nucleosynthesis is considered.

Phys. Rev. C 9, 1813 (1974) - Published 1 May, 1974

Show Abstract

Angular distributions for the elastic and inelastic scattering of $α$ particles from the even Ni isotopes from 12.5 to 177.5° in the energy range from 18-27 MeV are reported. The $β_{2}$ coupling strengths to the first excited $2^{+}$ state in each isotope are extracted from the data and are compared to similar results obtained at higher energy. The lack of any backward enhancement in the cross sections, in contrast to results reported for lighter nuclei, is explained on the basis of the level densities in the compound system.

Excitation functions for ( $p, n$ ) reactions to 25 MeV on ${}^{63}{Cu}$ , ${}^{65}{Cu}$ , and ${}^{107}{Ag}$

Phys. Rev. C 9, 1819 (1974) - Published 1 May, 1974

Show Abstract

Absolute cross sections for the ( $p, n$ ) reactions on ${}^{63}{Cu}$ , ${}^{65}{Cu}$ , and ${}^{107}{Ag}$ at proton energies from 2.5 to 25 MeV were determined by the activation method. Metal foil targets of natural isotopic abundance were used; therefore, the results for ${}^{63}{Zn}$ above 22.3 MeV and for ${}^{107}{Cd}$ above 18.8 MeV include contributions from ( $p, 3 n$ ) reactions. Beam intensities were measured with a Faraday cup. Disintegration rates of the product nuclei were determined by assaying their $γ$ rays with calibrated Ge(Li) detector systems. Comparisons of the present cross sections are made with a complete compilation of previous measurements and with calculations based on a Monte Carlo intranuclear-cascade-statistical-evaporation model. Half-lives for ${}^{63}{Zn}$ and ${}^{107}{Cd}$ were determined to be 38.0 ± 0.1 min and 6.50 ± 0.02 h, respectively.

Show Abstract

30 states in ${}^{85}{Kr}$ were investigated via the ${}^{84}{Kr} (d, p) {}^{85}{Kr}$ reaction using 11.0-MeV deuterons. At least 22 of these states have not been previously reported. Angular distributions were measured from 20 to 160° for transitions to 25 of these states, and were fitted with zero-range distorted-wave Born-approximation calculations. Excitation energies, $l$ values, spectroscopic factors, and the implied values of $J^{π}$ are given. Comparisons are made with states of other nuclei having both one neutron less and one neutron more than the $N = 50$ shell closure.

Radiative decay of neutron resonances in ${}^{73}{Ge} (n, γ) {}^{74}{Ge}$

R. E. Chrien, D. I. Garber, J. L. Holm, and K. Rimawi

Phys. Rev. C 9, 1839 (1974) - Published 1 May, 1974

Show Abstract

$γ$ rays following neutron capture in natural germanium have been studied up to $E_{n} \approx 500$ eV with the fast chopper at the Brookhaven high flux beam reactor. Up to this energy only resonances in ${}^{73}{Ge}$ contribute. From the high-energy $γ$ rays observed, levels in ${}^{74}{Ge}$ are identified to an excitation energy of about 3 MeV. From the low-energy $γ$ rays depopulating the ${}^{74}{Ge}$ levels, spin assignments for several ${}^{73}{Ge}$ resonances are made; namely 102 eV, $J^{π} = 4^{+}$ ; 204 eV, $J^{π} = 5^{+}$ ; and 224 eV, $J^{π} = 4^{+}$ . The results of the resonance capture experiments are compared to previous "average-resonance" and thermal-capture work, and in general are found to be in good agreement. Average radiative strengths for $M 1$ and $E 2$ transitions are calculated and compared to model estimates.

Show Abstract

The unbound states up to 10.477-MeV excitation energy in ${}^{29}{Si}$ were studied with the ${}^{28}{Si} (d, p) {}^{29}{Si}$ reaction. Experimental angular distributions were analyzed by use of distorted-wave Born-approximation calculations according to the Vincent-Fortune method, and neutron resonance widths were calculated from the measured cross sections of each state for the possible neutron single-particle assignments $2 p_{\frac{3}{2}}$ , $1 d_{\frac{3}{2}}$ , and $1 f_{\frac{7}{2}}$ . Several $l$ values were determined by comparing the neutron widths extracted from the ( $d, p$ ) data with neutron widths previously measured in the ( $n, γ$ ) and ( $n$ , total) experiments.

Decay of the $22 - μ s$ isomeric state of ${}^{38}K$

Phys. Rev. C 9, 1857 (1974) - Published 1 May, 1974

Show Abstract

The decay of the $22.5 - μ s$ isomer of ${}^{38}K$ has been studied by observing the delayed $γ$ rays following the ${}^{22}{Mg} ({}^{16}O, p n) {}^{38}K$ and ${}^{35}{Cl} (α, n) {}^{38}K$ reactions. $γ$ -ray singles and $γ - γ$ coincidence measurements were made and the reaction threshold for production of the isomer was determined for the ( $α, n$ ) reaction. The 3458-keV metastable state decays by an apparent $E 1$ transition ( $α_{T} = 0.58$ ) to a level at 3420 keV and by an 812-keV transition to a level at 2646 keV. The isomerism is understood in terms of the selection rules for the decay of $E 1$ transitions in $T = 0$ nuclei. A weak-coupling estimate of the excitation energy of the $7^{+} {(1 f_{\frac{7}{2}})}^{2}$ state in ${}^{38}K$ yields a value in excellent agreement with that observed for this isomer.

Collective multipole expansion of the inelastic scattering continuum

M. B. Lewis

Phys. Rev. C 9, 1878 (1974) - Published 1 May, 1974

Show Abstract

The differential cross sections for the high-energy inelastic scattering continuum are estimated by a direct-reaction model. The amplitudes for the expected collective multipoles were obtained from sum rules. An approximation method was applied to estimate an infinite multipole expansion. It was found that most of the relatively high-energy continuum cross sections in the ( $p, p^{'}$ ) reaction could be accounted for by this collective multipole model. The theoretical angular distribution of the high-energy continuum in this model is in reasonable agreement with measured cross sections over the entire angular region studied.

Variational calculation of light nuclei using nearly orthogonal functions

N. E. Reid, N. E. Davison, and J. P. Svenne

Phys. Rev. C 9, 1882 (1974) - Published 1 May, 1974

Show Abstract

A Hartree-Fock-like variational calculation which is specifically directed toward the treatment of axial and triaxial deformations in light nuclei is presented. By choosing Cartesian harmonic-oscillator wave functions to be the trial wave functions and taking the oscillator length parameters $b_{x} [= {(\frac{ℏ}{m ω_{x}})}^{\frac{1}{2}}]$ , $b_{y}$ , $b_{z}$ in each major oscillator shell to be the variational parameters, the capacity for deformation is built into the wave functions from the outset and a substantial reduction in the calculational effort is achieved. These variational wave functions are not strictly orthogonal, but the effects of this approximation appear to be relatively unimportant. A realistic two-body effective interaction is employed which depends on the average density of the nucleus under consideration. It is constructed from nuclear matter theory and has been shown to contain the most important physical aspects of the Brueckner $G$ matrix. The shapes of the intrinsic states of $4 n$ nuclei are found to be more complicated than simple spheroids or ellipsoids, often exhibiting large hexadecapole moments. Ground-state properties including binding energies, rms charge radii, and multipole moments are calculated and found to be in accord with experimental results and earlier calculations.
